Final answer:
The passage describing Cleopatra as 'how respectable and amiable at once,' along with mentioning her fortitude, clearly conveys admiration for her and her rare qualities that made her a role model.
Step-by-step explanation:
The line from passage 4 that best expresses the speaker's view that Cleopatra was someone to be admired is: "How pleasant she is, how kind, how respectable and amiable at once - two qualities rarely found in the same person. Indeed, she will be a woman whom later we can show our wives, from whose fortitude men too can draw an example, whom now while we can still see and hear her we admire as much as those women whom we read about." This excerpt from the text implies that Cleopatra's character combined rare qualities that garnered respect and made her an example worthy of admiration, both for men and women.
